Easy Air Intake - Green Filter

3641 Views 11 Replies 9 Participants Last post by  rufatiwe
I’ve owned 2 4c’s, both with the Eurocompulsion intake. Not trying to bash them, but I never liked how tight the filter fit to the maf housing. I really had to force it on. The prev owner of my current car clearly wrecked the filter trying to get it on.

So, I went with a simple option - a green filter (great brand, excellent quality, IMO - used them many times) attached to the stock maf and intake tube. $75, remove the stock air box and stick this filter on. Easy. Same performance as the kits out there.

It slid on the maf housing with minimal effort, no soap or oil or forcing needed. A rain sock can be purchased separately - I had it from the EC kit. I also used some zip ties to secure the tube.

Part number 2302 - Link

Is the new filter taking air from the hot part of the engine compartment rather than the side duct vent? That wouldn't be a good idea.
My mind is in cycling mode and noticed the Huffy box first.
How did you figure out that part 2302 was the right filter (I do not see an ALFA option on the Green Filter website)? Closest fit/measurements from the EC filter? It certainly looks handsome next to the EC one, which seems to have gotten mangled. Thanks.

Haha - good eye. Their box’s have nice thick cardboard for a cold garage floor :).

It will get plenty of fresh air there... not as good as the enclosed stock box, but the same as other aftermarket kits. The fender vent will feed air directly to it, the bottom of the cone aligns with the stock cutout too. Plus it’s far from exhaust and in an area with lots of fresh air (if that makes sense).

They are excellent quality filters. Better than K&N IMO. As I mentioned above, used them for years, in daily drivers too. It’s heavier, more rubber on both ends, and has a thicker filter element than the EC filter.

I just searched the cone filter section for the dimensions I thought would work. It’s basically the same size as the EC filter but with a larger base to fit the maf housing better.

The EC filter got mangled trying to get it on the maf housing (prev owner) - if you haven’t tried, it’s an unreasonably tight fit. My last 4c, I had a hard time getting it on without ruining it like this one.

The EC is very difficult to get on the maf housing especially if you installed it thru the wheel well without taking the rear fender off. I am about to do cam belt this weekend and looking to see how my filter look after 5 years of use. Might be an excellent time for replacement.

Used Green filters in the past also. Good quality. I've used the Twister version. Comes with a top notch alu housing (for rain/heat protection) (y)

Thanks OP, I thought the same thing when installing my EC V2.
Green Filter PN 2895 looks to be the same size/spec but gray in color......maybe a little cheaper too. Vivid Racing shows them in stock for $53.61 + shipping.

Not cheaper but I've been thinking about this BMC carbon fiber filter. It's available in multiple sizes. It has an attached carbon fiber shield. And, it's Italian

I recently just put a new green filter on my stage 2 ec air intake. I will say that decent way nothing and to go out and replace it with a carbon fiber filter is complete Overkill. Especially considering that where it's at you'll never be able to see it.
Has anyone installed a carbon filter from BMS?

Also does anyone know what is the size of the connection to throttle body and turbo? If we know the size we should be able to select from the catalogue.
